Battle Tactics for the Western Front
The Trench system

The trench system that developed was anathema to the High Command, who tried the most obvious methods of overcoming it. In practical terms, this meant extended artillery bombardment to destroy wire and emplacements, which it conspicuously failed to do. By the time the attacking force had left their trenches the opposing lines were bristling with rifles and machine-guns. Advancing British soldiers were forbidden to fire at the enemy, but were required to hold their rifles at the port (across their chests), and tackle the enemy with grenades and bayonets. These tactics failed again and again, and many units adopted more flexible methods of attack to try to reduce casualties. It was not until 1917 that tactical doctrine began to change, with creeping barrages that moved with the infantry, tank support to deal with strongpoints, and fire and movement tactics within infantry platoons to enable them to get forward in the attack.


Hindenburg Line


Hindenburg and his quartermaster general, Erich von Ludendorff, decided to build a system of German defence fortifications behind the northern and central sectors of the Western Front. Constructed between the northern coast and Verdun, each sector had its own system of mutually supporting strongpoints backed up with barbed wire, trenchworks and firepower.

Flame Thrower

Flame-throwers were first used at the Western Front in October 1914. Operated by two men, they were mainly used to clear enemy soldiers from front-line trenches. At first they had a range of 25 metres but later this was increased to 40 metres. This meant they were only effective over narrow areas of No Man's Land. Another problem was that the flame-thrower was difficult to move around and only contained enough oil to burn 40 seconds at the time. Soldiers who operated flame-throwers had a short-life span because as soon as they used them they were the target of rifle and machine-gun fire. The British Army also experimented with flame-throwers. However, they found short-range jets inefficient. They also developed four 2-ton thrower that could send a flame over 30 yards. These were introduced in July 1916 but within a couple of weeks two had been destroyed. Although these large flame-throwers initially created panic amongst German soldiers, the British were unable to capture the trenches under attack. With this failure, the British generals decided to abandon the use of flame-throwers.



Tunneling

On the Western Front during the First World War, the military employed specialist miners to dig tunnels under No Man's Land. The main objective was to place mines beneath enemy defensive positions. When it was detonated, the explosion would destroy that section of the trench. The infantry would then advance towards the enemy front-line hoping to take advantage of the confusion that followed the explosion of an underground mine. Soldiers in the trenches developed different strategies to discover enemy tunnelling. One method was to drive a stick into the ground and hold the other end between the teeth and feel any underground vibrations. Another one involved sinking a water-filled oil drum into the floor of the trench. The soldiers then took it in turns to lower an ear into the water to listen for any noise being made by tunnellers.



Infiltration

Infiltration tactics was an idea developed by General Oskar von Hutier in 1917. Instead of following Preliminary Bombardment with a massed infantry attack, small forces of experienced troops were sent forward to slip between enemy strong-points on the front-line. Once these soldiers were in a position to surprise the defenders, the infantry was ordered forward in a mass attack across No Man's Land.
